Choose the correct sequence for a 'Find your partner' activity to encourage speaking in an English language classroom: (K) Fold them into small squares, mix them well and put them into a bowl. (L) Each participant picks up a piece of paper and after reading it asks a question or gives a clue to find his/her partner. (M) List out pairs of matching items (e.g., historical figures, cartoon characters, or word combinations like bread & butter) and write them on separate pieces of paper. (N) The game is over when each participant has found his/her partner. (O) The participant who has the paper slip with the matching pair reads out his/her word or character.
